What This Guide Helps With
Error 242.4020 where low programmed rate causes excessive motor speed, risking inaccurate infusion delivery and unsafe dosing conditions.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Stop the infusion immediately
- Remove the pump from patient use
- Transfer therapy to a backup infusion device
Verify the Reported Error and Behavior
- Power on the pump and confirm Error 242.4020 is displayed
- Observe when the error occurs (startup, infusion start, or low rates)
- Listen for abnormal motor sounds or rapid movement
- Check for inconsistent or failed flow
Check Administration Set Compatibility and Installation
- Ensure a BD-approved Alaris administration set is being used
- Verify tubing is properly seated in the pumping channel
- Confirm correct routing through guides and sensors
- Fully close and latch the pump door
Inspect for Free Flow or Low Resistance Conditions
- Check all clamps are properly positioned
- Inspect for disconnected or loose tubing
- Ensure the set is not allowing uncontrolled free flow
Verify Infusion Programming
- Confirm infusion rate is appropriate and not extremely low
- Check VTBI and infusion mode
- Re-enter programming if needed
Inspect Pump Channel and Mechanism Area
- Check for fluid contamination or residue
- Inspect for debris or visible wear
- Clean per facility protocol if necessary
Power Cycle the Pump
- Turn the pump off
- Wait 10–15 seconds
- Restart and retest
Test with a Known-Good Administration Set
- Install a new BD Alaris-compatible set
- Perform a controlled test infusion
- Observe for normal operation
If the Problem Persists
If Error 242.4020 continues after all external checks, external and setup-related causes have been ruled out. The issue likely indicates motor control or encoder feedback failure.
- Remove the pump from service
- Label as Out of Service
- Send for repair or bench evaluation
Clinical Use Tip
Never troubleshoot or continue use on an active patient. Always transfer infusion to a verified working pump before evaluating errors.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"BD Alaris pump displaying Error 242.4020 with abnormal motor behavior at low infusion rate."
Cause
What was observed during troubleshooting.
Example:
"Ruled out administration set, setup, and programming issues; findings indicate likely motor/encoder feedback fault."
Resolution
What action was taken.
Example:
"Removed from service, labeled Out of Service, and sent to Biomed/vendor for repair and evaluation."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Motor and encoder-related errors directly impact infusion accuracy. Always rule out setup and resistance issues first, but escalate quickly when control reliability is in question. Patient safety depends on recognizing when to stop troubleshooting and remove the device from service.
That is successful troubleshooting.
